Method for burning burnable gas/combustion air mixtures, and burner for carrying out this method

摘要

According to a method for burning burnable gas/combustion air mixtures, at least two gas/air mixtures of differently proportioned compositions are supplied to the combustion region and burnt together, to be precise a mixture with a lower proportion of air in the region of the roots of the burner flames (4) produced during the burning of a mixture with the higher proportion of air. A burner suitable for implementing this method, with at least one elongated burner chamber (1) capable of being fed with such a mixture, has in the region of its mixture outlet openings at least one parallel-running burner tube (5) which serves as a conduit for a mixture with lower air content. At the mixture outlet openings of such a burner tube (5) there form maintaining flames (8) which ensure stabilisation of the burner flames (4) forming at the mixture outlet openings of the burner chamber (1) and are inclined to lift off when the proportion of air in the mixture supplied to them is comparatively high. <IMAGE>
